Design of Bionic Subsoiling Shovel and its Finite Element Analysis

The subsoiling shovel is the main tool for subsoiling in conservation tillage and its quality directly influences the effect of subsoiling. In this paper, based on the subsoiling shovel retrofit design, the research achievements of bionic techniques were applied to design the subsoiling shovel, and the three-dimensional models of modified subsoiling shovel and bionic subsoiling shovel were created through the software of Pro/E. Then apply Finite Element Method was used to do analog simulations for the two kinds of subsoiler. Analysis Result showed that the bionic subsoiling shovel reduced working resistance and the obvious phenomenon of stress concentration did not appear at the tip of bionic subsoiling shovel. Development design of bionic subsoiling shovel can effectively reduce the operation energy consumption and create great economic benefits.
